Modern Application Debugging: An Introduction To OpenTelemetry

summary
Claims that traces are the killer app for debugging and that OpenTelemetry supplies an open format, language SDKs, the OpenTelemetry Collector and OTLP for transporting metrics traces and logs. Demonstrations show a 10-language microservices demo (gRPC Redis Postgres Kafka) wired to Jaeger Prometheus Grafana and a ClickHouse exporter, collector pipelines that multicast and translate, and a span metrics connector that derives metrics. Expect Python overhead up to 20–30% in some cases.
